Daydream Island closed until mid-2018

Queensland's Daydream Island will stay closed until 2018 after being battered by Cyclone Debbie, with some staff expected to be made redundant.

Island operators have decided it doesn't make financial sense to try to reopen the tropical resort this year given a planned refurbishment was already approaching.

The more than $50 million redevelopment will instead be brought forward and the Whitsundays locale will reopen for guests in mid-2018.

In a statement, Daydream Island Resort and Spa said it was reviewing staffing needs and some redundancies would be necessary "in the short term".

"Many staff have already moved on to other jobs, and Daydream is working closely with other operators including Hamilton Island to assist with possible redeployments," general manager Dawson Tang said.

Meanwhile, Hamilton Island welcomed its first guests since the cyclone on Saturday.

The clean-up effort from the cyclone and subsequent flooding is also continuing on the mainland.
